PROBLEM TO BE SOLVED: To provide an operative mechanism configured to, even when a drive part is in a non-driven state after an operation member is driven by the drive part to be moved to a predetermined position, automatically move the operation member further from the predetermined position and move the operation member to a desired position.SOLUTION: An operative mechanism M includes an operation member 1 configured to move from an initial position via an intermediate position to an operation position, a drive part 2, and an elongated member 3, one end of which is connected to the drive part 2, and an auxiliary mechanism 4 configured to connect to the other end 3b of the elongated member 3 and to the operation member 1. The auxiliary mechanism 4 includes a base body 41 and an elastic member 42. In accordance with the movement of the elongated member 3 driven by the drive part 2, the auxiliary mechanism 4 moves the operation member 1 to the intermediate position in a state where the elastic member 42 is elastically deformed. Then, in a state where the operation member 1 is not driven, the other end 3b of the elongated member 3 and the base body 41 are moved relative to each other by elastic force of the elastic member 42 and the operation member 1 is moved from the intermediate position to the operation position.SELECTED DRAWING: Figure 2
【課題】作動部材を駆動部により駆動させて所定の位置まで移動させた後に、駆動部が非駆動状態であっても、作動部材を自動的に上記所定の位置からさらに移動させ、作動部材を所望の位置まで移動させる作動機構を提供すること。【解決手段】作動機構Mは、初期位置から中間位置を介して作動位置へと移動する作動部材1と、駆動部2と、一端が駆動部2に接続する長尺部材3と、長尺部材3の他端3bと作動部材1とに接続する補助機構4とを備え、補助機構4は、基体41と、弾性部材42とを有し、補助機構4は、駆動部2の駆動による長尺部材3の移動に伴って、弾性部材42が弾性変形した状態で作動部材1を中間位置まで移動させ、作動部材1の非駆動状態において、弾性部材42の弾性力によって長尺部材3の他端3bと基体41とが相対移動して、作動部材1が中間位置から作動位置へと移動する。【選択図】図2
